Always get "Active: failed" on 'sudo systemctl status mongod' command

Question

I followed this link to install MongoDB on my machine. Everything was fine and it worked. Currently, when I run sudo systemctl status mongod, I get this error:

● mongod.service - High-performance, schema-free document-oriented database
   Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since سه<U+200C>شنبه 2019-05-21 15:50:14 +0430; 25min ago
     Docs: https://docs.mongodb.org/manual
  Process: 5278 ExecStart=/usr/bin/mongod --config /etc/mongod.conf (code=exited, status=1/FAILURE)
 Main PID: 5278 (code=exited, status=1/FAILURE)

مه 21 15:50:14 [my-username] systemd[1]: mongod.service: Failed with result 'exit-code'.

This is what I have done after it was ok, that might have caused the problem:

I decided to add mongodb extension using pecl. I was not able to make a new database, neither by MongodDB Compassm, nor by Sell.
I uninstalled it.
I installed it from the same link and ran the same commands, but when I wanted to install it again, after running sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6 command, I got gpg: unchanged: 1 at the end, not gpg: imported: 1 (RSA: 1) which I got for the first time.
I even deleted and recreated my dbPath folder (/var/lib/mongodb) which seems that the problem is somehow associated with this parameter which is on /etc/mongod.conf.

When I run sudo systemctl status mongod, I still get Active: failed.

What should I do to run MongoDB properly again and make its status Active: Running?

Update: This is my /etc/mongod.conf file:

# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# Where and how to store data.
storage:
  dbPath: /var/lib/mongodb

Can you please add more of what `journalctl -u mongodb` shows? — Joe Doherty, May 21 '19 at 12:11
Have you tried starting it using `sudo systemctl start mongodb`? I don't see that you tried to start in manually, just reinstalling etc. Probably you have restarted your machine after the first installation? — Florian Schlag, May 21 '19 at 12:19
Did you make data/db/ directory using sudo mkdir -p /data/db ? Also can you post your mongod.conf file? Maybe also do a sudo apt update then sudo apt install -y mongodb and then see if your sudo systemctl status mongodb command works — smitty_werbenjagermanjensen, May 21 '19 at 12:37
I faced all those solutions during my searches and they did not work for me. I update my question with `mongod.conf` file. — Majid Alaeinia, May 21 '19 at 12:40
I think it looks okay your .conf file unless I'm missing something and what is the exact error when you enter systemctl start mongod .. Have you tried just a sudo reboot as listed here and the other thing https://stackoverflow.com/questions/37565758/mongodb-not-working-on-ubuntu-16-04 — smitty_werbenjagermanjensen, May 21 '19 at 12:51
I faced this post on my searches, but I do not have `mongodb-27017.sock` on my `/tmp/` directory. I did tried rebooting multiple times. — Majid Alaeinia, May 21 '19 at 12:56
What if you update in your /etc/mongod.conf the line where it says dbPath: /var/lib/mongodb too dbPath: /data/db — smitty_werbenjagermanjensen, May 21 '19 at 13:07
What is the output of the following ? sudo service mongod start.. Also it may be good to follow official MongoDB docs https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/ — smitty_werbenjagermanjensen, May 21 '19 at 13:45
Also in the tutorial it says to be using Ubuntu Server are you using that or Ubuntu Dekstop? Make sure you adhere to the prereqs — smitty_werbenjagermanjensen, May 21 '19 at 14:02
Thanks for your time, but I did exactly whatever you mentioned in your answers, before asking this question. — Majid Alaeinia, May 21 '19 at 14:20
All right the last thing I can think of is just uninstalling it and reinstalling it again. Sorry I couldn't help — smitty_werbenjagermanjensen, May 21 '19 at 14:23

I solved the problem by uninstalling MongoDB and installing a specific version of MongoDB, not the latest version, using this link. This might not be the actual solution but works for now.
